I believe whenever we design an experiment we have to communicate with clarity and precision in order to be able to reproduce an experiment with the same results, everything has to be standardized and specified. In my biology class designing experiments is the same, at the start of the year i was told to design an experiment, and that failed terribly because i was vague about the amount of of substance to use or the duration of each trial. Similarly, when i first designed experiments in chemistry i was also vague about how large of a beaker to us, how much water to add, the timing, and the significant figures to use. In my mind then, i would have been thinking it's just a beaker or this amount won't make any difference but now i would think that the amount of times i had to rewrite an experiment is troubling and that in order to make an experiment viable this was needed.
In the oobleck experiment in which my group and i designed, other people in the class had to look over it and make sure that they could understand every aspect of it and be able to do it step by step without any confusion. We recieved the paper with a few comments, as show below.
However, when we completely fixed it the experiment was not carried out successfully since the measurements that we took were very inaccurate due to the coin being able to fall through the oobleck really quickly or the coin not falling through the oobleck at all because it was too thick. In the end we had to redesign an experiment, which invovled testing out how fast different concentrations of oobleck will fill up a petri dish.
